torch.nextafter — PyTorch 2.7 documentation (original) (raw)

torch.nextafter(input, other, *, out=None) → Tensor¶

Return the next floating-point value after input towards other, elementwise.

The shapes of input and other must bebroadcastable.

Parameters

• input (Tensor) – the first input tensor
• other (Tensor) – the second input tensor

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

eps = torch.finfo(torch.float32).eps torch.nextafter(torch.tensor([1.0, 2.0]), torch.tensor([2.0, 1.0])) == torch.tensor([eps + 1, 2 - eps]) tensor([True, True])
